Proposal Penelitian Teknik Industri (1)

Monday, November 9th, 2009

Industrial engineer is a branch of engineering that concerns with the development, improvement, implementation and evaluation of integrated systems of people, money, knowledge, information, equipment, energy, material and process. It also deals with designing new prototypes to help save money and make the prototype better. Industrial engineering draws upon the principles and methods of engineering analysis and synthesis, as well as mathematical, physical and social sciences together with the principles and methods of engineering analysis and design to specify, predict and evaluate the results to be obtained from such systems. In lean manufacturing systems, Industrial engineers work to eliminate wastes of time, money, materials, energy, and other resources. di kutip dari situs ini. 

Dari definisi diatas, saat akan melakukan penelitian berbasis konsep diatas, maka persoalan yang muncul adalah bagaimana membuat proposal penelitian teknik industri. Materi ini dibuat berdasarkan beberapa permasalahan yang muncul saat saya memberikan materi penelitian di teknik industri. Sebelum memperluas lingkup bahasan di kajian penelitian teknik industri, alangkah lebih baik bila lingkup kajian teknik industri ditelaah lebih dalam. Berikut adalah cuplikan lingkup kajian teknik industri yang diambil dari wikipedia : 

Industrial engineering is also known as operations management, management science, systems engineering, or manufacturing engineering; a distinction that seems to depend on the viewpoint or motives of the user. Recruiters or educational establishments use the names to differentiate themselves from others. In healthcare, for example, industrial engineers are more commonly known as management engineers or health systems engineers.

The term “industrial” in industrial engineering can be misleading. While the term originally applied to manufacturing, it has grown to encompass virtually all other industries and services as well. The various topics of concern to industrial engineers include management science, financial engineering, engineering management, supply chain management, process engineering, operations research, systems engineering, ergonomics, value engineering and quality engineering.

Seperti beberapa panduan penulisan proposal (contoh lihat di situs ini) hal pertama kali yang perlu diperhatikan adalah latar belakang masalah. Berikut saya sampaikan beberapa tips untuk menyusun latar belakang masalah yang baik.

1. Apakah ada informasi tentang permasalahan yang secara riil sedang dihadapi oleh perusahaan. Informasi ini biasanya diperoleh saat mahasiswa melakukan kerja praktek, magang, atau lewat jejaring konsultan. Bila ada maka pokok permasalahan telah anda temukan tinggal diformulasikan lebih baik. Bila belum maka perlu penelitian awal untuk mengidentifikasi apakah ada permasalahan tertentu di perusahaan.

2. Mengumpulkan data/bukti riil dari perusahaan bahwa masalah tersebut memang sedang dialami oleh perusahaan. Data ini juga dapat diperkuat dengan data yang dipublish di jurnal ilmiah, majalah, koran, atau website yang dapat dipertanggungjawabkan bukti kebenarannya.

3. Membuat diagram sebab akibat untuk mencari akar masalah dari permasalahan awal. Serta tetapkan indikator yang digunakakan sebagai ukura kinerja masalah.

4. Membuat pointer logika penyampaian masalah yang runtun dan mengalir dengan baik.

5. Deskripsikan pointer logika dan diagram sebab akibat dengan narasi yang baik ( mengguanakan bahasa Indonesia yang baik dan benar). Data pendukung silahkan ikut dicantumkan menjadi bagian dari narasi tersebut. Bila data terlalu banyak maka dapat diletakkan pada  bagian lampiran proposal.

6. Baca ulang hasil tulisan anda dan mintakan orang lain untuk memberikan komentar latar belakang masalah yang baru saja anda buat. Lakukan perbaikan dan ulangi untuk meminta bantuan orang lain untuk memperbaiki latar belakang.

Nah harapannya dengan proses iterasi tersebut, maka latar belakang yang dibuat memiliki mutu yang baik.

Good news!

Monday, April 7th, 2008

Indonesia’s economic growth is forecast at 6 per cent this year, down from 6.4 per cent predicted earlier, in line with a slowing of the country’s exports sparked by a world economic slowdown, the World Bank said on Tuesday…

However, it predicted Indonesia’s economy growth would rise to 6.4 per cent in 2009…

Despite the slowing global economy, in 2007 Indonesia’s economic growth accelerated to a 10-year high of 6.3 per cent, the World Bank said.

“This growth rate reduced (Indonesia’s) poverty rate from 17.8 per cent (in 2006) to 16.6 per cent (in 2007), based on the government’s poverty line,” it said.

The growth rate also reversed the recent trend toward jobless growth by causing unemployment to fall from 10.3 per cent to 9.1 per cent.

This is good news; and it is from the World Bank, which often offers gloomy prediction of Indonesia’s economic growth.

I am not a macroeconomist, but I am willing to bet that the economy this year will grow faster than 6 percent, maybe close to last year’s growth rate of 6.3 percent.

Malnutrition makes you less educated

Wednesday, December 12th, 2007

In Indonesia, more than 30% of children under the age of 5 years suffer from chronic malnourishment. The long-term consequences of childhood malnutrition are well established in the literature. Yet, little is known about the extent to which these children are able to recover from some of the long-term deficits in health outcomes caused by childhood undernourishment. To capture the association between nutritional deficiency at young ages and subsequent health status, a panel data is constructed using observations on children between the age of 3 and 59 months in 1993 who are followed through the 1997 and 2000 waves of the Indonesian Family Life Survey. A dynamic conditional health demand function is estimated, where the coefficient on the one-period lagged health status captures the extent of recovery, if any, from childhood malnutrition. This coefficient is also known as the ‘catch-up’ term. … [A] coefficient of 0.23 estimated here indicates that by adolescence, a malnourished child will grow to be only 0.95 cm shorter than a well-nourished child…

That is Subha Mani of the University of Southern California in a recent job market paper. She concludes “poor nutrition at young ages will cause some, but not severe, retardation in the growth of future height indicating partial catch-up effects”.

Once centimeter is still pretty large, I think. Besides, she also calculates that malnourished child will also have 0.6 less year of schooling.

Thanks to Arya Gaduh for the pointer.

Are Indonesia’s poverty rates declining?

Saturday, October 27th, 2007

An old post by Arya Gaduh of Nalar Ekonomi caught my attention. It is about Indonesia’s latest poverty rates published by Statistics Indonesia (BPS): It reports that the number of Indonesian poor declines by 2.13 million, or about 1.2 percentage points (from 17.75% to 16.58%).

The fall is not statistically significant, however, as Arya correctly suggests.

A back of envelope calculation gives me a standard error of the difference in the poverty rates of about 2 percentage points. It is so large so that it may overwhelm the estimated difference.

It means we cannot really say whether the poverty rate last year (17.75%) is really different from the rate this year (16.58%).

In that sense, the BPS’s press release is rather misleading. It reports that poverty rate declines, but it does not tell us the standard error of the fall.

It is as if BPS gets the number of the poor from the entire Indonesia’s population, not from a small sample of it only.

Of course, I am glad to hear that poverty rate falls. But, at the same time, BPS should acknowledge that there is too much noise in the data. That we do not really have convincing evidence that poverty rate has actually declined.

Banks comply with capital requirements?

Saturday, September 22nd, 2007

Using dynamic panel data models, we examine the effect of capital requirement on banks’ behavior in Indonesia. We find inconclusive results. Banks tend to comply with capital requirement: They increase their capital ratio when their CAR is lower than, or falling towards, the eight percent regulatory minimum. However, most of our results are statistically significant at 20-30% level of significance only. Moreover, our results are mostly driven by private domestic banks and heavily-undercapitalized banks that were closely monitored by regulator in the aftermath of the 1998 crisis. Whether, in normal circumstances, banks in developing countries like Indonesia comply with capital requirement, therefore, remains questionable.

That’s from another recent working paper by Parinduri and Riyanto. Comments and suggestions are welcome.

Indonesian economy grows faster

Saturday, August 18th, 2007

Almost seven percent in the second quarter this year. If we exclude oil and gas sectors, that is.

Indonesia’s economic growth (2002-2007)

Indonesia’s economy as a whole grows by 6.3%, which is also quite good. But, the slower growth is because oil and gas sectors continue contracting.

If this seven percent growth translates into lower unemployment- and poverty rates, all would be very well.

Strategic sale works

Sunday, August 12th, 2007

We examine the effect of strategic sale—the sale of banks to strategic foreign investors—on banks’ performance. The Government of Indonesia implemented such a policy as a part of bank restructuring in the aftermath of the 1998 banking crisis. Using difference-in-difference models, we find that strategic sale leads to 12%-15% cost reduction. These results are robust to the use of other estimators such as difference-in-difference matching-estimators and stochastic-frontier analysis, to that of other performance measures such as return on assets and net interest margin, and also to that of different types of samples. These suggest that strategic sale could play an important role in restructuring troubled banks in developing countries.

In short, the sale of Indonesian banks to strategic foreign investors a couple of years ago is a good thing.

That’s from a recent working paper by Parinduri and Riyanto.
